Stigmella magnispinella Remeikis & Stonis, in Stonis et al. 2016f: 571 –572, figs 4, 5, 17–20, 29–32, 38, 39.

Material examined. 1 ♂ (holotype), PERU, Dept. Ayacucho, 35 km W Puquio, 14°47'31"S, 74°27'19"W, elevation about 3370 m, 10.iii.1987, O. Karsholt, genitalia slide no. RA 544♂ ( ZMUC) ; 2 ♀, Dept. Ancash, 35 km SE Huaraz, Cerro Cahuish, Quabrada Puvadvado , 9°39'05"S, 77°13'34"W, 3870 m, 18.ii.1987, O. Karsholt, genitalia slide no. RA 548♀ ( ZMUC) .

Diagnosis. Belongs to the Stigmella magnispinella group. The combination of very wide lobes of uncus, two large apical processes of valva, short ventral plate of vinculum, and specific set of cornuti distinguishes S. magnispinella from all members of the group.

Male ( Fig. 34 ). Described in Stonis et al. 2016f: 572, figs 38, 39. Forewing length 2.3 mm; wingspan 5.1–5.2 mm.

Female. Similar to male.

Male genitalia. Illustrated in Stonis et al. 2016f: figs 4, 5, 17–20.

Female genitalia. Illustrated in Stonis et al. 2016f: figs 29–32.

Bionomics. Adults fly in February–March. Otherwise biology unknown.

Distribution ( Fig. 9 ). Known from two localities in the Andean Peru (Dept. Ayacucho and Ancash) at elevations ca. 3370–3870 m ( Fig. 12 ).
